Better. Those lines are saying you are using the group lookup in an
access control list which cannot do group lookups or any other kind of
delayed (async) data lookup.
The answer is needed immediately by the access control and all Squid has
to work with is DUNNO / "insufficient data".

The -d parameter on the helper command line for Squid helpers produces
their internal debug.
